Thunderbird Already Has Contact Sidebar Built In...!Rated 1 out of 5 stars

I have no idea why anyone would want to go through the time and trouble to create this, as Thunderbird has always had a Contacts Sidebar built into it.

In any new email window, just press the F9 key and the address book sidebar appears... This has been a feature of Thunderbird like.... forever....

Press "Write" to bring up a new email window, press F9, and the Contacts sidebar appears. You can right click on an item in the sidebar and a context menu will come up showing you different options that are available, like "create a new address book" or "add contact", etc.

Thank you Sparky!Rated 5 out of 5 stars

This is not to rate the original developer's work (he seems long gone :-( ) but Sparky's effort to bring this invaluable add-on forward to newer versions of TB! The revised add-on works flawlessly under 38.3. That is one fine job you did here! One can find the download here: http://sparkyio.com/cs/
